Engineering students make 'Quadcopter'

Tirupati: A team of five final year engineering students of ECE stream made a new technological device 'Quadrajet' helicopter aka 'Quadcopter' as part of their project. Dilip Kumar, a final year engineering student of Sri College of Engineering and Technology, Mallavaram near Yerpedu, along with four other students made this copter by spending Rs 45,000. These students termed this invention as 'Quadcopter' as they used four propellers so as to operate and used Wi-Fi technology. Usually, helicopters use only one or two propellers, but this has four. They will control the speed of propellers through 'Android' based mobile phone. The entire project is meant for rescue operations and for surveillance needs. Speaking to The Hans India, Dilip said, "Being an engineering student I have opted for this project as part of project work." "I used 12 volts battery which can last for fifteen minutes in the air. If we increase the battery capacity we can send this 'Quadcopter' to a height of 200 feet and can fly it in the air for a long time. I made this for special needs like for rescue operations. In certain conditions, human beings may not enter the spot. Especially, when a terrorist attack takes place, the entry of human being is dangerous, and during that situation, we can send this 'Quadcopter' to know the condition. For this I kept one high definition camera and one VGA camera to record visuals and shot pictures. I have provided a storage devise like 'pen drive' as well as an option to save it in mobile itself", he explained. This 'Quadcopter' is useful wherever the entry of human being is impossible and dangerous, and one can direct this copter by giving commands from a mobile, he added. They have spent more than six months to make this and we felt happy on seeing the ultimate result, he said. When mobile phone is not reachable due to lack of signals, the 'Quadcopter' can be operated through Global Positioning System (GPS), he said. The next target is to make 'Hexacopter', which runs with six propellers and few additional features, he replied to a query.
